IEC 60794是一个系列规范，本部分规定了光纤、电缆元件、电缆结构要求、安装和操作条件的主要要求、电缆设计特性和OPPC（光相导体）的测试，OPPC用于承载电流以及通信和数据传输。可根据IEC TR 62839-1建立相应的环境声明。OPPC是包含光纤的传统相裸导体的替代品。通常，纤维松散地嵌入保护缓冲管中。为满足机械和电气要求，一层或多层铝、铝合金、铝包钢、镀锌钢或其混合物的铠装采用螺旋绞合。 购买本文件时可获得的所有当前修订均包含在购买本文件中。

This part of IEC 60794, which is a family specification, specifies the optical fibre, cable elements, cable construction requirements, main requirements for installation and operating conditions, cable design characteristics and test for OPPC (optical phase conductor), used for carrying current as well as communication and data transmission. The corresponding environmental declaration can be built according to IEC TR 62839-1.The OPPC is a substitute for a conventional phase bare conductor containing optical fibres. Usually, the fibres are embedded loosely in protective buffer tubes. To fulfil mechanical and electrical requirements, an armouring of one or more layers with aluminium, aluminium alloy, and aluminium clad steel, galvanized steel or a mixture of them is helically stranded.All current amendments available at time of purchase are included with the purchase of this document.
